Hey guy’s this tv has been in my parents house for over 5-6 years and it has been like this for well over 4 years. We thought it’s dead pixels from the start until today , I decided to mess with the tv settings and upgraded the firmware. When watching anything, it shows up as a dark patch, whether it be a much darker yellow background then the rest of the background or black. We ran a picture test and as you can see the pixels look good in that area, maybe a little bit darker, but in the menu grey / black area you can still see it. What can be the cause of this.? Samsung UN60EH6050 is the model # 60inch tv
Hi @alexstreet , Try the following: Disconnect the power from the TV. Remove the back cover from the TV and disconnect the cable that goes between the mainboard and the power board. Reconnect the power to the TV. The TV LED backlights should all turn on (there will be no picture because the mainboard is disconnected). If the dark patch is still there you have a LED backlight problem, most likely some faulty LEDs in the backlight array
